% jpaper provides two modes:
% In addition to the usual options leqno and fleqn, jpaper also provides the
% following additional flags (each of which can be turned on by specifying the
% flag as an option, or turned off by specifying "no"flag as an option):
% * lineno: Enables line numbering. This may be useful while editing.
% * pageno: Enables page numbering. This is useful for anything that is not
% * hyperref: Enables the hyperref package. While the hyperref package is
%   normally convenient for your readers, IEEE PDF-eXpress does not allow it.
%
% The default set of options is camera,nolineno,nopageno,nohyperref.
